device not in device manager

hi
having problems with htc sync but cannot fix this until i at least get the phone to appear in device manager
at the moment, which i plug it in via usb (official htc cable) it charges but nothing shows in device manager so cannot even update drivers etc
running 32 bit win 7
any solutions welcomed
thanks

Once the relevant drivers have been installed, and your phone has been connected as an drive, it should show up under Disk Drives In Device Manager.
Download HTC Sync from here: http://www.htc.com/www/SupportDownloadList.aspx?p_id=312&act=sd&cat=3
Esnure that you have USB debugging enabled:
1. From the Home screen, press MENU, and then tap Settings > Applications > Development.
2. Make sure the USB debugging check box is selected.
After you have installed HTC Sync, turn off the phone and turn it back on again while connected to the PC via the USB cable, and then select the Disk Drive option.

if it only shows as disk drives, then it still wont work.
You should have an 'ADB devices' section at the top (or it might be called ADB interfaces, it's been a while since i did it on 7)
here, the phone should show as 'My HTC'
chances are that windows 7 decided it knew better and went and installed an 'HTC Dream adb composite device' from windows update instead of the ones installed by HTC SYnc
delete those or update manually to the My HTC ones and you should be good.
The disk drives is for the SD card and has nothing to do with the sync at all as far as i know.

thanks for the response, but the device just will not show in device manager
i have tried the above steps
any other solutions

Computer finding G4 through ADB

Has anyone gotten their computer find their G4 through cmd (adb devices). I cant get the adb message on my phone to allow access to my computer. I turned on and off usb debugging several times but i still don't see the message on my phone to allow access. I let me computer download the drivers when plugging up my G4 as well as allowing the install of PC drivers.

yes, working great for me. Do u have updated and right drivers? u find tread here with right drivers..
Sent from my unlocked and rooted LG-H815

I was having the same problem..
You need to install the LG Drivers and then your phone will connect via adb..you will be asked on your phone to allow the port connection after installing the proper LG drivers. Verify and you will be good to go..
I used these ones below in the attatchment or you can grab them from.....

I think I found the issue. I had Note 3, 4, Nexus 6, S6 edge, and G4 all still on my computer in the device manager. I uninstalled all of them plus I uninstalled the adb driver in device manager. Plugged my G4 back in and ran the PC driver update via G4 and it worked. I can now see my G4. Don't know if I had to do all that to get it working but hey it worked for me.

I was having issues with this myself and didn't find a solution. I found out that I was having better luck switching it to Camera PTP from the notification dropdown. Sometimes I have to toggle to MTP back to PTP, The dev notifcation should appear when it is actually connected.
1. PTP
(1a. switch to MTP back to PTP if it doesn't work)
2. 'adb kill-server'
3. 'adb devices'
-If you see your device, you can try to 'adb connect **IP**' but it will most likely say it was unable to connect
4. give it your adb commands you want
It's the only way I've been able to get adb, hope this helps!

I was having this issue also. After install win10 then adb connection to my LG G4 (h818) was not detected. Back to android.com, it said that if general USB driver doesn't work then we must find OEM driver to the producer web. LG ADB Driver was about 17MB. After installed the driver then it was immediately detected. Thank God, finally.

I have silly problem. I bought used G4 LG from someone found in online forum. Checked all series on phone (sticker), on software "about phone" all showing LG H815 software version H81510H, but by adb ( linux machine ) showed H812xxxxxx .... set on developer option debugging the command "adb reboot bootloader" just send device into android boot ( device boot ). I wish to unlock the bootloader and put CM. Hard button option > pushing vol up + power button simultaneously did nothing, vol up + power button then > connect to PC via usb, did nothing ( just send phone to device boot ) ..... I have no windows machine

Google drivers not working on Nexus 5X/Marshmallow on Win7 - Is the phone too new?

I have my new Nexus 5X with Android 6 on it. I am trying to unlock and root.
I have enabled USB debugging and OEM unlock.
I have downloaded and installed the SDK package with Platform-Tools and drivers in the 'Extras' folder.
When first plugging in the phone I install the drivers with the 'Have Disk' and browse method.
Every time, installing the driver returns an Error 'Code 10 - device cannot start. 'Android ADB interface' shows up in device manager when I plug in the phone but with an exclamation point.
I have uninstalled, downloaded fresh drivers from other sources, reinstalled, tried plugging the phone in while in 'recovery' mode (starting by pressing all 3 hardware buttons).
I uninstall every time and reboot both the computer and the phone. The drivers simply won't work.
What is going on here? Is the phone/Android 6 still too new to unlock and root?
P.S. I should also say that I go into Developer options and change the Select USB Configuration between PTP and MTP (between which, I have not seen mention of the correct choice. Does it not matter?) - I cannot chose the others RNDIS, Audio Source, or MIDI; it seems to want to default to 'Charging' when I try to change to these choices.

Having the same issues on Windows 8.1. Can't get my 5x to connect to transfer files or to show up in adb.

Just need the right drivers. Download the driver files from here: https://www.dropbox.com/sh/e43knzpxvr9hzqi/AAC7Yiz8EShMpFiMkClPpkC5a?dl=0
1. Then with the phone plugged in and in PTP mode go into the device manager on your PC.
2. You'll probably have an Android device listed with an exclamation point showing. Right click on it.
3. Pick update driver.
4. Pick browse my computer for driver software.
5. Then pick "let me pick from a list of device drivers.
6. Then pick have disk.
7. Navigate to the folder you downloaded and select android_winusb
8. Let it install and you should be ok

I was running into the same issue. The problem is you need to install them first as an ADB Interface Device (not composite) with the phone on and plugged in. From Device Manager choose the Google | Android ADB Interface (not the composite one. I saw another reference to making sure it's in PTP mode which may force it to this one as well but I didn't test). Then when you get into FastBoot mode on your phone and plug it in you can go through the same Update Driver steps and choose the "Android ADB Interface" for it as well when it shows the Nexus 5 with the yellow triangle. Then you should be good to go.

Sorry. I should have been more specific. Part of it is I did so many different approaches they've bled together in my head and I was on my way out the door yesterday when I fired off the reply.
To try to break it down from memory (going to throw in a couple of different options since I can’t seem to fully uninstall / reinstall so please provide any corrections once you get it to work or let me know if anything doesn’t match what you find and I’ll try to remember from there):
Phase I (phone on and connected to computer):
Open Device Manager. My phone shows as Android Device | Android Composite ADB Interface or Android ADB Interface.
If it is the Composite version, I believe I had to update it to the straight “Android ADB Interface to get Phase II to work)
If you don’t see that, look to see if you have any uninstalled devices by scanning for new. If so, then right click on that device, and choose “Update Driver”
Choose “Browse my computer for driver software”
Choose the “Have disk” option and browse to your USB Driver folder
From there, choose “Google | Android ADB Interface”
Phase II (phone in recovery connected to computer)
On phone, choose “Update device from ADB”
Open Device Manager and you should see the Nexus 5 under Other Devices with the yellow triangle.
Right click on it and “Update Drivers”
Choose “Browse my computer for driver software”
Choose “Let me pick from a list….”
Choose “Android Device”
Choose “Android ADB Interface”
Now you should be able to push the update over

Simple method: What I did was plug it in and wait for it to show up in device manager. Then I deleted the device (the one that shows adb) from device manager. Then I unplugged the device and plugged it back in... Then waited for drivers to install on it's own. Everything was good after that.

I have no trouble other than on Windows 10. Windows 10 doesn't even show the drivers from a list to install.

I followed this to get my Nexus 5X detected on my Windows 10: http://stackoverflow.com/questions/...ould-we-use-for-the-nexus-5/19839812#19839812

I have no trouble with Fastboot or adb. It only happens when I try and sideload. I end up have to use my Macbook Pro to sideload.

I wish it were that easy. But, no, this does not work. Nor do I believe my issue is the same as you others here, as I have Windows 7 and not the 8.1 and 10 issues that you are having.
No, no matter what driver I use, including any from your kind link, bsinc1962, they return an error, code 10 when trying just to install the drivers. I cannot go further.
What is this Code 10 error preventing drivers from installing?

Unknown USB device (failed request for device descriptor)

I have a problem.
My screen is broken. Now I want to send him to OnePlus.
But before that I want unroot it. Or at least reset to factory defaults. But both things fails.
I have the latest FreedomOS Rom. Since then I can no longer use TWRP. When I start my phone to the recovery the screen goes black and nothing happens anymore.
The same happens when I put it back to factory settings through the settings menu .
I've read there is a modified version of TWRP.
From here begins the real problem. Windows doesn't recognizes my phone.
In Device Manager it appear as "unknown USB device (failed request for device descriptor)"
What I've tried:
Boot in to Bootloader
Original (Dash) USB cable
Other USB cable
WIndows 10
Windows 7
USB debugging on
USB debugging off
OEM unlocking on
OEM unlocking off
USB configuration: File transfer
USB configuration: MTP
USB Configuration: Charge
Anyone have an idea?
Maybe it's the ROM. But I cannot flash another ROM because I can not get into TWRP.
Maybe it's an option to flash the modified TWRP without a computer. So right from the bootloader. But I do not know if this is possible. And how it should be done

I'm having the exact same problem. Did you find a solution?
In windows 10 -> i get Device Descriptor Request Failed
In windows 7 -> Unknown Usb Device (Installed Correctly)
whenever i try to update device driver with ANY driver (oneplus... or generic sdk driver) I get a message saying "doesn't contain a suitable driver for your device.....)

I went to device manager > right click mtp (unknown device) > update driver software > browse my computer > let me pick > mtp USB device > happy me

Windows it's the problem. I reinstalled drivers, adb, nothing. At work i try it & it works. I reinstalled windows. Now works.
I'm on windows 10 x64.

Damn it, I don't think windows is my problem.. i tried Windows 10 / Windows 7(2 diff computers)
i can't even see the phone as MTP..

Found any solution to this? Having a similar issue

Phone does not connect

It just doesn't show up in ADB devices. However, when I change ROMs it does, but gives me an error when trying to mount "not permitted"
Amazon was of no help. They gave an add on link to enter into SDK manager but it would fail every time... something on how it failed to update the status to complete. I'll add images later.
Can anyone help me with this? In case stuff goes south with my phone, I want to have a chance at recovery through ADB.
(Other notes: Win7 32-bit, ran as admin, enabled USB debugging from developer options, added site on SDK manager)
